'A' Tournament is "Based on the approval of the Championship Committee." Tier numbers are halved (80) for single gender schools. Tier count must be done on or before October 2 of the current year.

For tiering classification, Member School population numbers will be determined using the previous year's September 30th numbers as submitted in the 1701 Form. There will be an appeal process for one year to the next for Member Schools requesting to have their numbers reviewed due to a substantial discrepancy with the numbers from the previous years. (Please refer to policy C7.1 in Section III). BC School Sports will use the previous year's September numbers for grades 10 and 11 for the current years senior population numbers.
